Dropdownlist Regression in 19.2 : Support for Enum arrays is broken

[Joseph Tan]

Hi There,

This was working really well in SF Blazor  19.1.069 : 

public enum TestEnum  
{ 
value0 = 0,
value1 = 1,
value2 = 2
}

protected TestEnum[] EnumList = Enum.GetValues<TestEnum>();

protected TestEnum EnumVal ; 

<SfDropDownList TValue="AssetCategory" TItem="AssetCategory" DataSource="@AssetCategories" @bind-Value="@theAssetCategory"/>

But now throws an exception in 19.2.0.49 when the list is expanded

[12:06:22 WRN] Unhandled exception rendering component: Object reference not set to an instance of an object.System.NullReferenceException: Object reference not set to an instance of an object.   at Syncfusion.Blazor.DropDowns.SfDropDownList`2.ListFocus()   at Syncfusion.Blazor.DropDowns.SfDropDownList`2.CreatePopup()   at Syncfusion.Blazor.DropDowns.SfDropDownList`2.ShowPopup()   at Syncfusion.Blazor.DropDowns.SfDropDownList`2.DropDownClick()   at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task)   at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle)
